Error Code P002B: What It Means & What To Do?
OBD Code P002B - B Camshaft Profile Control Circuit Low Bank 1
A sudden increase in the fuel consumption and the engine performance along with occasional engine stalling and not starting may be an indication of problem with the camshaft, thus indicating OBD Code P002B Error where “B” is an indicative of problem with Camshaft Profile Circuit Control.
Therefore, OBD Code P002B - “B” error refers to the
timing discrepancy between the fuel injector and exhaust camshaft.

OBD-II Code Decreased engine performance is defined as a "B"
Camshaft Profile Control Circuit/Open.
Signals from the camshaft sensor tells about the proper engine timing by
checking the fuel pressure systems and the exhaust and sending the information
to the ECM to properly time the engine performance. Newer vehicles use a
variable timing system to adjust the timing of the camshaft in relation to the
crankshaft to increase fuel efficiency and performance. If the Camshaft is not
in the proper position relative to the crankshaft, the PCM will set code P002B.
What causes this problem with the
Camshaft Profile Circuit Control?
- Lack of Engine Oil consistency and level maintenance
- Use of incorrect and/or contaminated engine oil
- Defective/Damaged Oil Solenoid
- Faulty Camshaft/Crankshaft Sensor and wirings of the sensor
- Fault within the PCM/ECM (Powertrain Control Module) sensors or
electricals
- Stuck/Damaged Valve
Replace/Repair These Parts To Fix OBD Code P002B
- Camshaft Sensor - One of the major problems may arise
with the camshaft sensor. It is the first thing checked by the technician.
Visit us today to get all camshaft related replacement parts.
- Crankshaft Sensor - Any problem in the crankshaft with
directly hamper the engines performance. Replace faulty sensor now!
- Powertrain Control
Module - The
most frequent problems can always be due to faulty powertrain module sensors
and wiring. Find all the Powertrain related parts with us.
- Timing Belt And
Pulleys - Faulty
engine timing belt and its parts are a direct problem to the engine’s
performance. Immediately replace the damaged components.
- Seal Valve - Before going for the parts, first
look for the smaller issue that can be the reason for the error, thus resulting
in that check engine line on indication. Replace old seal valves now.
- Fuel Volume Control
Solenoid - Faulty
solenoid can affect the fuel injection system, reducing its efficiency,
indicating the OBD Code P002B. Thus, it’s needed to be replaced immediately.
- Fuel Pressure
Regulator - P002B error code may also flash due to irregular
fuel pressure which in turn hampers the engine’s performance. Replace the fuel
pressure regulator now.
- Fuel Pump - A leaky and/or damaged fuel pump will not be able to supply proper fuel to the engine resulting in engine stalling and sometimes not starting. Immediate replacement of damaged fuel pump is advisable.
- Diagnostic Tool - In order to be
that DIY guy, you need few diagnostic tools to get your car problems pointed
out easily. Our diagnostic tools collection will come handy to do so, so why
not have a look?
Symptoms Of OBD Error Code P002B
OBD Code P002B
may flash due to improper fuel injection into the engine as well as problem
with the exhaust. There is typically an illuminated Check Engine light as well.

- Issue of altered
power band
How To Correct P002B "B" Camshaft Profile Control Circuit Low Bank 1
Oil plays a crucial role in protecting the engine’s internal parts from damage, keeping the engine cool and preventing contaminants from accumulating inside the engine. Throughout the normal course of your car’s operation, the oil’s ability to perform these crucial roles is minimized due to contamination from moisture and combustion gases. If you take a lot of short trips where the engine doesn't reach full operating temperature on a regular basis, the oil will become contaminated more rapidly requiring more frequent oil changes.
The oil filter also needs periodic replacement because over time it loses its ability to clean the oil as the engine is operated. If the oil filter is not changed regularly it can degrade and in severe cases even disintegrate, which can plug up oil passages and lead to engine damage or failure.
Some of the common fixes for the problems in the OBD Code P002B for all
makes and models are as follows;
- Make sure there
is enough clean oil in the engine and usage of vehicle specific engine oil
- Check for any
problem with the fuel injection system and/or the fuel pump
- Check for proper
engine operation and engine timing, as well as for cooling system leaks
- Replace camshaft
and crankshaft sensor and check for any issue with the wiring of the modules
- Check for any
electrical connection issue with the PCM (Powertrain Control Module) and
replace if can’t be corrected
- Replace old and
damaged stuck valve

Easy Diagnosis Of Engine Error OBD Code P002B
P002B is properly
diagnosed with an advanced scan tool capable of factory sensor readings (not
just one from an auto parts store). A qualified technician can read the data
from the advanced scan tool to determine when the problem occurred, or if it is
still occurring. They may clear the code/light and test drive the vehicle while
monitoring the scan tool data to see if the fault returns or is present.
Based upon the
conditions of the test, possibly clearing the code, and road testing the car
while monitoring the data, further diagnosis may be required. Diagnosis may
require multiple tools such as:
- Verify the code
by hooking the vehicle up to an OBD-II scanner and check for other codes.
- Record the data
along with freeze frame data, and the codes are then cleared to see if they
reoccur.
- Wiring and
connectors to be checked for loose connections, corrosion, or shorts.
- Test the camshaft
and crankshaft sensors using specialized tools and also test the components that
may help pinpoint the problem, as well as inspection of the timing chain or
timing belt.
- If there is a
physical problem with the timing belt this could cause the timing to go off far
enough to trigger a code P002B.
Common Mistakes When Diagnosing OBD Code P002B
Oftentimes the
camshaft sensor is repaired and replaced, without checking the timing chain or
belt for damage or stretching. Since there are many reasons for the error code
P002B, all the components must be examined properly first to avoid any
unnecessary changes and increasing the expenses.
